Project-Details

The Portland Metro region is experiencing growth in population, jobs and travel leading to severe congestion along freeway corridors. Severe congestion results in recurring safety hot-spots and reduced system reliability. The Portland Region Traffic Performance Report​ provides a foundation for monitoring the health of the regional freeway system using the following key performance categories: congestion and bottlenecks, reliability, safety (related to crashes and incidents) and speed/delay. The 2020 report covers traffic performance in 2019 (the most recent year of non-pandemic influenced data), which enables ODOT to identify problems and manage the system to facilitate the efficient movement of people, goods and services. The 2020 report also shows that targeted highway investments in traffic bottleneck locations have significantly improved highway performance in terms of improved travel time reliability, reduced delay and fewer crashes. 

Beginning March 14, 2020, ODOT traffic analysts noted a significant drop in daily traffic volume on major freeways in the Portland metropolitan region and a substantial decrease in total travel time.  After Governor Brown's stay-at-home order issued March 23, 2020 traffic volume continued to decrease, with the fewest amount of average weekday vehicles occurring the week of March 30-April 3, 2020.  Region 1 traffic analysts monitored traffic volumes, travel times, and incidents on Portland's major freeway corridors (I-5, I-205, I-84, I-405, OR 217, and US 26) to better understand the impacts of Covid-19 on travel patterns.  Reports from March 2020 through January 2022 are available upon request.
